To all wiiom may concern:

it known l, Ai'limsr Lyon, citizen oi the United States, and resident of Phihflelphie, cour lhiladclphia, State of 'll 'emisylveuia, have mode a certain new and useful invention Relating to Billier-firttechiiig Devices, of which the following z; specification taken in connection with "the accompanying drawing.

" 's invention. relates especially to buffer 3' devices adapted to attach Lyon er type buffers to the front of Overor generally similar automobiles.

attachment comprises extension sup- IOPlHgI'blilCkQtS which may be formed oi mo cubic irou, drop forgings or other suitable material and the brackets are preterulfily formed with angular or flanged stiffeningportious and with it butler aligir log flange on the front of each bracket eguiust which the edge of the spring strip other buli cr attaching); member may be cleumed or connected as by one or more connecting bolts passing through these parts.

' The rcu attaching end of thebracket may be slotted to cooperate with an attaching bolt or device secured to the automobile frame mere 'ir and an intermediate portion of the brecl t is preferably provided with definite aligning fiiinges or membcrs vhich may onboth chore and below one or more of irzime flanges or other portions of the nu nuobilc to definitely support or align this port of the bracket which may be clamped in this position as by at ill-bolt clzmipiiig device. I

be used with other types or styles of buffers or bumpers which preferably have rearwardly extending Spring strip or other attaching members. As shown in Figs. 1 and 2, the illustrative butler may comprise the spring strip attaching membi rs 7, each curvlug out 11rd at 6 to form the end loops 5 of the butter from which these spring strips may extend inward into adjustably overlapping or reenforcing position at 3, 4 where the strips may be clumped or connected by the clips or clamping devices 8, 9.

The extension supporting brackets may, as shown in Fig. 3, be formed of malleable iron and may each have adjacent its front end one or more bull'er aligning flanges 11. extending laterally from the substantially vertical portion or taco 10 of the bracket in which butler connector portion the square or other apertures 21 may be formed. These apertures may accommodate the oquare or other noncircuhir shanks of the connector bolts 33 extending v therethrough and through suitable holes in the attaching arms or members 7 of the butter so as to rigidly and Securely connect these parts shown in Figs. 1 and 2. The intermediate portion of each bracket is preferably securely bolted to the automobile rume or connected portions of the machine and is formed with one or more aligning flanges or members to definitely hold this part of the bracket in the desired vertical position in connection with the cooperating clamping devices. For this purpose a single or duplex aligning flange may be formed on the inner face of the bracket so that the groove or channel 16 thus formed may closely embrace or wedge around the edge of the frame flange Ell which in this type of automobile eX- tends outward on both sides of the machine from the frame web 32', the upper fienge also being outwardly bent in a similar way. A lower aligning yoke such as 18 is preferably formed at this part or" the bracket so that the curved socket 19 thus provided. may portly embrace the depending cushion support 25 in which the rubber or other cushion 2'? is mounted torcooperation with the other parts of the automobile. This cushion support or casingmuy have flanges at its upper portion rigidly bolted as by the bolts 26 to the frame flange so as to provide a good support for this part of the bracket.

This intermediate part of the bracket adjacent these aligning devices is preferably formed with strengthening flanges such as 22 and with holes 17 through whichthe arms ea of the U-bolt clamping device 20 extend so that this clamping device can be tightened by the nuts 24 and lock washers 23 around the upper port-ion of the cushion sup-port or casing and thus strongly and rigidly holdthe bracket in the desired aligned position, Of course where this duplex aligning flange cooperates with the lower frame flange the bracket is curved down as at it adj scent-this point and the rear attaching end of the bracket 12 may, as indicated in Figs. 2, 3 and at, be upwardly inclined where it is desired to have this attachingend connected to the upper frame flange 30. For this purpose one or more holes or slots such as 18 may be formed in this bracket end and a stud bolt or other attaching device 29 may extend therethrough to securely attach the bracket end to the frame in connection, if desired, with the lock washer 28.

Of course these attaching devices may be most eifectively' applied by first clamping and connecting the brackets to the frame members and then clamping the somewhat loosely connected buffer strips to each bracket after which the buffer front clips or members may be clamped in their desired adjusted position which is advantageous if excessive strains on the connecting bolts or devices are to be avoided.
